2 SHEETS-SHEET 2- VICTOR EMILIUS HANSEN, OF BROOKLYN, NEW YORK, ASSIGNOR TO INTERNATIONAL CIGAR MACHINERY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

CIGAR-WRAPPER CUTTER.

To all whom it may concern Be it known that I, VICTOR EMILIUS HAN- SEN, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Cigar-Wrapper Cutters, of which the following is a Specification.

This invention relates to an improvement in cigar wrapper cutters for cigar machines.

In cigar machines heretofore known, there has been employed a wrapper cutting bed inclosing a cutting die upon which a leaf from which a wrapper is to be cut is spread.

"These machines further employed one or more rollers normally movable across the wrapper bed and die to effect the cutting of a wrapper from the leaf. In the operation of such machines there is danger of injury to the hands of an operator engaged in spreading a leaf upon the bed and die, unless the hands are removed therefrom before the cooperating cutting roller is advanced. I-Ieretofore, various mechanisms have been devised to prevent suchinjury by stopping or slowing the machine as a Whole, or the wrapper cutting mechanism, when the operator is tardy in removing the hands from the cutting bed and die after having spread a leaf thereupon. While such devices were successfully operative, they were not entirely satisfactory because of their complicated character and liability to derangement or breakage. Moreover, stoppage 0f the machine in such cases resulted in a loss of production for the machine, which of course increased the cost of the cigars made thereupon.

The main object of the present invention is the production of a cigar wrapper cutter adapted foruse on cigar machines in which the danger ofinjury to an operators hands is eliminated without stoppage of the machine or any part thereof.

A further object is the production of a device of this general character which is simpler, more durable and less expensive than those heretofore lmown.

With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying draw ngs, which form a part of this specificatlon and in And Fig. 5 is a detail view, partly broken away, of the bracket supporting the coiiper ating cutting member; and of the mount for said member.

In carrying the invention into effect, there is provided a wrapper bed and a cutting die within said bed, the two being shaped and arranged so that a leaf from which a Wrap-' per is to be cut may be spread over the top thereof, and held thereon by suction or any other suitable means well known in the art. There is further provided a cooperating cutting member normally movable across the wrapper bed and cutting die to effect the separation of a shaped wrapper from the leaf. There is further provided means operative by an obstruction upon the wrapper bed and cutting die, such as an operators hands, for causing the cooperating cutting member to be swung from its normal position and to pass the Wrapper bed and cutting die without crossing the same, so that danger of injury to the operators hand is eliminated without stopping the machine or any part thereof.

In the best constructions, there is provided a post and means for reciprocating the post a definite distance along one side of the wrapper bed and cutting die, and upon this post is pivotally mounted a bracket carrying the cooperating cutting member or members. In the best constructions also, the cut-.

ting members are pivotally and yieldably mounted inthe bracket above referred to.

In the best constructions also, a trip mechanism is employed for causing the cooperating cuttingv member to swing from its normal path to a path alongside the wrapper bed and cutting die. I

All of the above elements may be varied in construction within wide limits. The particular device selected to illustrate the invention is but one of many possible concrete em bodiments of the same, and the invention therefore is not to be restricted to the precise detailsof the structure shownand described. Moreover, certain parts of the invention are capable of use independent of other parts, and such independent use is contemplated.

In the device selected to illustrate the invention, 6 indicates the main bed of a cigar machine in connection with which the device is used, and 7 indicates a bracket secured to the bed 6 and adapted to support a wrapper bed 8 and cutting die 9, both of a type well known in the art. The operator spreads a leaf from which a shaped wrapper is to be cut over the wrapper bed 8 and cutting die 9, where the leaf is held by suction established within the wrapper bed 8 and cutting die 9 by means not shown in the drawings, but which are well known in the art and which are omitted herefrom in the interest of brevity and clearness. Cooperating with the die 9 is a pair of cutting members or rollers 10. Each of these rollers 10 is mounted upon cone pivots 11 which are threaded or otherwise secured in a bracket 12. Each bracket 12 is pinned or otherwise secured to one end of a short shaft 13. This shaft is journaled in a bracket 14. Upon the other end of each shaft 13 ispinned or otherwise secured an adjusting arm 15 and this arm is engaged by an adjusting screw 16 threaded in a suitable projection extending from the bracket 14. Coiled around each shaft 13, at points intermediate its ends, is a torsion spring 17, one end of which is secured to the bracket 14 and the other end of which is secured'to a collar 18 loosely mounted upon the shaft 13. Each of these collars is provided with a series of radial slots adapted to engage a pin 19 extending through the shaft 13. By means of the mechanism just described, it will be understood that movement of the rollers 10 in a downward direction is limited by the arms 15 and adjusting screw 16, and"that movement in an upward direction is in opposition'to the force exerted by the torsion spring 17, so that the cutting members or rollers 10 are pivotally,

' yieldably and adjustably mounted in the bracket 14.

The bracket 14 is pivotally mounted upon a post 20. This 0st is given a reciprocating movement a de ite distance alongside the wrapper bed 8 and cutting die 9 to cause the rollers 10*to roll overthe edge of the die 9 and cut a wrapper from the leaf over lying the bed and die. To efiect this movement, the post has attached thereto a rack 21 which is in mesh with and is operated by the gear wheel 22. The gear wheel 22 is fast upon one end of a short shaft23, and upon the other end of'this short shaft is fixed a pinion 24. The pinion 24 is in mesh with a sector gear 25 formed on a cam lever 26, which lever is fast on a short shaft 27 journaled in bearings formed in a bracket 28 supported on the main frame 6. The cam le- .to thebracket 14 before referred to.

ver 26 carries a bowl 29 which tracks in a cam groove 30 formed in a cam 31, and this cam is fast upon a shaft 32 which is one of the main cam shafts of the cigar machine in connection with which the device is used.

For the purpose of guiding the post 20 in its reciprocatory movement, two studs 33 are provided which studs are held in place in the post by means of a set screw 34. The studs support rollers 35. The lower roller 35 tracks on a rail 36 secured to the bed 6 before referred to. The upper roller 35 tracks under a rail 37 which rail is supported at one end by a bracket 38, this being the bracket which supports the short shaft 23 before referred to. The other end of the rail 37 is supported by a bracket 39 rising from the bed 6 before referred to.

The mechanism thus far described provides the means whereby the rollers are normally reciprocated across the wrapper bed 8 and cutting die 9. or the purpose of causing the bracket 14 carrying the cooperating cutting rollers 10 on thepost 20, in the event of an obstruction such as an operators hand being upon the wrapper bed and cutting die as the rollers advance, to swing from their normal position and pass without crossing the wrapper bed and cutting die, holding means are employed for holding the cutting rollers 10 in their normal position, and a purpose of holding them in their normal po-- sition, there is provided a plunger 43 which is slidable in the upper part of the bracket 14. This plunger 43 engages a recess or slot 44 formed in an enlarged head 45 carried by the post 20. This slot or recess ex tends around the periphery of the enlarged head 45 for 90 degrees, and at each end thereof is sunk a' depression marked 46. The plunger 43 normally. engages one of these depressions, thus holding the bracket holding means to keep" the rollers 10 in their position shown in full lines in the figures; or in other words, in their normal operating position. Means are provided, however, for disengaging the plunger'43 from the depressions at one end of the recess or slot 44 so that the torsion spring 40 may swing the bracket about the 0st. This means includes a lever 47 which is fulcrumed at 48 One end of this lever lies in front of the brackets lies when the plunger 43 is operating as holding means to keep the rollers 10 in their normal operating position. As the cutting rollers advance toward the die 9 in the direction of the arrow in Fig. 2, and in the event of an obstruction such as the operators hand being upon the die at the time, the free end of the lever 47 will come in contact with said obstruction and will be stopped thereby. In broken lines in Fig. 2, at the position marked B, the lever'47 is shown in the position it will occupy when it has met an obstruction. It will be readily understood that in such event, the plunger 43 will-be withdrawn from the depression 46 and that the torsion spring 40 will immediately cause the bracket 14 carrying the cutting rollers 10 to swing backwardly from the position in which they are shown at B out of their normal path; and it will be seen by an inspection of Fig. 4, that there is a rise in the recess or slot 44 so that when the mechanism is tripped, the bracket 14 and of course the cutting rollers carried thereby will not only be released so they will swing, but will be lifted by the plunger 43 moving around in the shallow part of the slot 44 so that an operators fingers cannot be pinched during this backward swinging movement of the bracket and rollers. The swinging movement is limited by the plunger 43 coming in contact and engaging the depression 46 at the other end of the slot. At C, in Fig. 2, the parts are shown in broken lines in the position to which they swing;and it will be readily understood that they will be locked in that position by means of the plunger 43 engaging the second depression 46 in the head 45 until purposely released and brought back to normal position after the obstruction has been removed.

In view of the foregoing, a detailed description of the device is deemed unnecesr sary, and is omitted herefrom in the interest of brevity.
